Modifying Crafting Components

Changing a single entry

With KubeJS it is possible to modify the predefined components of existing GTCEu Modern machine crafting recipes. You can replace singular entries, or do bulk modification of components. -1 is defined as a fallback value if no other entries exist. if you modify in bulk, you MUST insert one if the component expects it to exist. otherwise the game may crash when loading recipes. Other numbers correspond to tier indices. for example: 3 == GTValues.HV

modification.js

const Map = Java.loadClass("java.util.Map")

GTCEuServerEvents.craftingComponents(event => {
    event.modifyItem(CraftingComponent.CIRCUIT, GTValues.MV, Item.of('minecraft:dirt')) // (1)
    event.modifyItem(CraftingComponent.PUMP, Map.of(
        GTValues.FALLBACK, Item.of('gtceu:lv_robot_arm'),
        GTValues.LV, Item.of('gtceu:lv_robot_arm'),
        GTValues.MV, Item.of('gtceu:mv_robot_arm'),
        GTValues.HV, Item.of('gtceu:hv_robot_arm'),
        GTValues.EV, Item.of('gtceu:ev_robot_arm'),
        GTValues.IV, Item.of('gtceu:iv_robot_arm'),
        GTValues.LuV, Item.of('gtceu:luv_robot_arm'),
        GTValues.ZPM, Item.of('gtceu:zpm_robot_arm'),
        GTValues.UV, Item.of('gtceu:uv_robot_arm'),
    )) // (2)
    event.modifyTag(CraftingComponent.CASING, GTValues.EV, 'minecraft:logs') // (3)
    event.modifyUnificationEntry(CraftingComponent.PLATE, GTValues.UEV, new UnificationEntry('plate', 'gtceu:infinity')) // (4)
})

1. Replaces the MV circuit tag in all GT machine crafting recipes with a single block of minecraft:dirt.
2. Modifies all pumps in GT machine crafting recipes by replacing the pump with a robot arm, and reinserts the FALLBACK entry.
3. Replaces the EV casing with the #minecraft:logs tag. note the lack of # at the beginning of the tag!
4. Adds a new entry to the plate component for UEV with prefix plate and material gtceu:infinity.

Bulk Callbacks

All the bulk callbacks (modify* functions that take two parameters instead of three, see example 2) work the same as the single modification functions, except they take a map of int: value instead of a single entry.

Creating new components

It's also possible to create new crafting components with KubeJS. You must add entries for all tiers you're planning to use, and a FALLBACK if the map may be indexed out of bounds at all. It's recommended to always add a FALLBACK entry.

creation.js

const Map = Java.loadClass("java.util.Map")

let ITEM_CRAFTING_COMPONENT = null
let TAG_CRAFTING_COMPONENT = null
let UNIFICATION_CRAFTING_COMPONENT = null

GTCEuServerEvents.craftingComponents(event => {
    ITEM_CRAFTING_COMPONENT = event.createItem(Map.of(
        GTValues.FALLBACK: Item.of('minecraft:cyan_stained_glass'),
        GTValues.LV: Item.of('minecraft:cyan_stained_glass'),
        GTValues.MV: Item.of('minecraft:cyan_stained_glass'),
        GTValues.HV: Item.of('minecraft:cyan_stained_glass'),
        GTValues.EV: Item.of('minecraft:lime_stained_glass'),
        GTValues.IV: Item.of('minecraft:lime_stained_glass'),
        GTValues.LuV: Item.of('minecraft:lime_stained_glass'),
        GTValues.ZPM: Item.of('minecraft:magenta_stained_glass'),
        GTValues.UV: Item.of('minecraft:magenta_stained_glass'),
    )) // (1)
    TAG_CRAFTING_COMPONENT = event.createTag(Map.of(
        GTValues.FALLBACK: 'forge:barrels/wooden'
        GTValues.LV: 'forge:chests/wooden'
        GTValues.MV: 'forge:chests/trapped'
        GTValues.HV: 'forge:chests/ender'
        GTValues.EV: 'forge:cobblestone'
        GTValues.IV: 'forge:cobblestone/normal'
        GTValues.LuV: 'forge:cobblestone/infested'
        GTValues.ZPM: 'forge:cobblestone/mossy'
        GTValues.UV: 'forge:cobblestone/deepslate'
    )) // (2)
    UNIFICATION_CRAFTING_COMPONENT = event.createUnificationEntry(Map.of(
        GTValues.FALLBACK: new UnificationEntry('plate', 'gtceu:infinity')
        GTValues.LV: new UnificationEntry('block', 'gtceu:infinity')
        GTValues.MV: new UnificationEntry('ingot', 'gtceu:infinity')
        GTValues.HV: new UnificationEntry('dust', 'gtceu:infinity')
        GTValues.EV: new UnificationEntry('round', 'gtceu:infinity')
        GTValues.IV: new UnificationEntry('foil', 'gtceu:infinity')
        GTValues.LuV: new UnificationEntry('longRod', 'gtceu:infinity')
        GTValues.ZPM: new UnificationEntry('rod', 'gtceu:infinity')
        GTValues.UV: new UnificationEntry('bolt', 'gtceu:infinity')
    )) // (3)
})

1. Creates a new crafting component with item stack entries.
2. Creates a new crafting component with item tag entries. note the lack of # at the beginning of the tag!
3. Creates a new crafting component with UnificationEntry entries.
